VILLAGRAN, E.; BERNAL, J.  e  AGUERO, M.. On the stabilization of bubble solitons. Rev. mex. fis. [online]. 2005, vol.51, n.6, pp.580-584. ISSN 0035-001X.

We analyze the instability of bubble soliton solutions for the cubic quintic nonlinear Schrödinger equation. This equation, for instance, can be obtained studying the nonlinear excitations of the DNA model. We have found that under specific restrictions concerning the main parameter of the model and soliton velocities, these solutions are stable.

Palavras-chave : Solitons; NSE; stability.
